Once everyone was gathered around the table, Isaac wasted no time. He had time to think before dinner on what he wanted to do. Though, the roasted chicken dinner on the table had such a good aroma, he wondered if he should eat first. Licking his lips, he felt like the food would be a good reward after he swaps his family around.
The family was seated around the dining room table. His mother and father were talking, while his brother Andy and sister Sarah were texting on their phones to their significant others. Chloe was not paying attention as she was humming a tune to herself. "This should be interesting. I hope this power even works." Isaac waved his hand as a flash of light blinded him for a second. As the light died down, he realized this power was no joke. First up, little Chloe's body with her pink skirt and white tank top had the head of his older sister Sarah.
"Andy, give my phone back you asshat!" Sarah reached and grabbed the phone out of her former hands, as Andy now had his head on his sister's sexy body. He wore a denim skirt and a halter top that showed his C-cups rather nicely. He reached and scratched his juicy tit and handed the phone back to his sister.
"Sarah, language!" Isaac's mother Jennifer berated her daughter. Her head was now on Andy's slightly muscular teenage body. She continued eating in her long sleeve green shirt and blue jeans. She scratched her new penis as she asked her husband, "Henry, can you pass the mashed potatoes?"
"Sure dear," said Henry, as he used his wife's painted hand to pass it over. He was on his wife's slightly shapely body. He had his large womanly butt shoved into a knee-length black skirt. His white top hung a bit low and showed the slightly sagging DD-cups in his purple lace bra. He reached in between his legs and fished out the panties between his pussy as well. Then, he lifted his leg and left out a fart.
"Ewww, daddy. Gross." This is when Isaac noticed the biggest elephant in the room. That statement came from little Chloe, who was now on her father's body. She was now easily the tallest in the family at 6' 1". She was wearing her dad's work polo tucked into khaki pants, secured by a brown belt. She also wore loafers on her feet. She used her large hairy hand to plug her nose, to not have to smell her dad's gas. Her beer gut hung over her pants a bit, and her pants also concealed what was easily the biggest penis in the family as well. Chloe also now had the biggest appetite of anyone in the family, for obvious reasons, as she shoveled down a whole plate in no time. Henry now had to watch his shape, though.
All the while, no one blinked or fidgeted or said anything. No one knew anything had happened. This was reality for every one. Isaac laughed suddenly, and the random fit garnered his mother's attention. She smiled, "What's so funny, Isaac?"
"Oh it's nothing, mom. Don't worry about it." Issac was also wondering how sex between his parents worked now. Sure, they were compatible. But, they had the bodies of his mother and brother, so it's kind of incestual, right? It made him cringe, but also made him laugh internally. He didn't care for his brother much, so he saw it as a fitting punishment. Though, his brother did have a sexy body now....which he might have to do something about...
Eating his chicken at last and making his stomach happy, Isaac knew his work here was done and left his family in this configuration...for now. He headed upstairs, passing by Chloe's room and swearing he could hear her moaning. She was already familiar with her new equipment. Well, they all were.
